Original Khojo Papers practice question — not from a past board paper.
Answer
Insect-pollinated flowers are large, brightly coloured and often scented, so insects are attracted to them. They produce nectar as a reward, and their pollen is sticky or spiny so it clings to the insect's body. The stigma is also sticky, and the anthers and stigma are placed where a visiting insect must brush against them.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Such flowers produce far less pollen than wind-pollinated ones, because the transfer is much more efficient.
